224 Blood Eosinophils, Immunoglobulin E, and Bronchiolitis Severity

Abstract

Conclusions: Based on this cohort review, CRS was not a highly sensitive or specific tool to discern the need for HFNC. Initiation of HFNC within the ED has shown to be an effective rescue modality for some patients in respiratory distress, but also requires costlier equipment and higher likelihood of PICU observation. It is therefore critical to develop a clinical support tool to help guide providers in the usage of HFNC in the ED. Additional refinement and validation of components within CRS (or other respiratory scoring tools) should be explored in order to establish guidelines and best practices for initiating HFNC therapy.
